FOLDING BOX.

SPECIFICATION forming part of Letters Patent No. 674,537, dated May 21, 1901.

Application filed December 20, 1900- Serial No. 40,549. (No model.

To all whom, it may concern: I

Be it known that we, HARRY B. MARLIN and JOSEPH L.BEOK, citizens of the United States,

vide a construction wherein the sides'andends will fold to lie in close relation and wherein the top may be slidably engaged with the body portion in both the set-up and knockdown positions of the body and will be held against dispacement and will in turn hold the elements of the body in their set-up or unfolded positions and their knocked down or folded positions.

Further objects and-advantages of the invention will be evident from the following description.

In the drawings forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views, Figure'l is a perspective view showing the box set up. Fig. 2 is a plan View of the box with cover removed and one of the sides folded part way inwardly. Fig. 3 is a section on line 3 3 of Fig. 1. Fig. 4 is a section on line 44 of Fig. 1. Fig. 5 is a perspective view showing the box folded. Fig. 6 is a section on line 6 6 of Fig. 5'. Fig. 7 is a section on line 7 7 of Fig. 5. Fig. 8 is a detail view, partly in section, showing a portion of the box with the means for holding the end of the cover in place.

Referring now to the drawings, the present box comprises a bottom 10, having supplemental side pieces 11, l2, l3, and .14: fixed to its edges and projecting thereabove to equal extents, and within the inclosure of these supplemental sides the main sides are hinged and into which they'are adapted to fold to lie below the upper edges of the supplemental sides. One of the main side pieces 15 is hinged with its lower edge in the corner between the bottom 10 and the supplemental side 11 and is adapted to lie against the bottom 10 or to stand erect against the inner face of the supplemental side piece 11. The hinge employed is a long pintle-rod 16, which is held to the lower edge of the side 15 by straps 17, additional straps 18 being also passed over this pintle-rod and secured to the bottom and the supplemental side 11. The pintle is held from displacement by the supplemental sides, at the ends thereof, and by reason of the loose engagement of both sets of straps with the pintle binding of the parts is prevented. A strip 19 is secured in the corner between the bottom 10 and the supplemental side 12 and is of a height substantially equal to the thickness of the side piece 15, and on the upper edge of this strip is disposed a pintle-rod 20, held by straps 21. A main side piece 22 is disposed with its bottom edge against the pintle-rod 20 and is held by straps 23, engaged loosely with the rod, so that the side 22 may be folded to lie upon the side 15. A third strip 25 is disposed between the bottom and the supplemental side 13, and to the upper edge of this strip is hinged a main side 26 by means ofthe long pintle-rod 27 and the straps 28 and 29, this side 26 being adapted to fold to lie upon the side 22. A fourth-strip 30, disposed in the angle between the bottom and the side piece let, has the fourth side 31 hinged thereto by means of the pintle-rod 32 and the straps 33 and 34.

Secured to the inner faces of the sides 15 and 22 are plates 35 and 36, respectively,which are bent around the corners of the sides to lie parallel with and spaced from the side edges of the said sides and projecting outwardly of the box when the sides are in their unfolded positions. Additional plates 37 and 33 are secured to the inner faces of the sides 26 and 31 and are bent upon themselves to form hook-plates, as shown, the bills of the hooks on each side 26 and 31 projecting toward each other. When the sides 26 and 31 are in their raised or unfolded positions, they are so spaced that when the sides 15 and 22 are subthere are secured additional plates 39 and 40 to the inner faces of said sides and bent with their upper edges or portions over the upper edges of the sides 15 and 22 and spaced therefrom, and these outwardlyproject-ing portions, which are bent over the upper edges of the sides 15 and 22, are adapted for engagement slidably by the hook-plates 41 and 42, which are secured against the under side of the top portion 43 of the cover of the box. Angle-plates 44 and 45 are secured to the under face of the top of the cover and spaced with their depending portions inwardly from the hook-plates to lie against the inner faces of the sides 15 and 22 and prevent inward folding of the said sides when the cover is in place. To permit inward movement of the cover to its place, slots 46 are cut in the upper edges of the sides 26 and 31, which receive the depending portions of these angleplates 44 and 45.

The cover of the box includes not only the top board or piece 43, but also the fixed side pieces or depending flanges 46, 47, and 48. To the inner faces of the flanges 46 and 48 are secured plates 49 and 50, which are bent outwardly under the flanges and spaced there-. from, and when the sides of the box are folded to lie within the inclosu re of the supplemental side pieces these plates 49 and 50 are adapted to be slidably engaged with similar plates 53 and 54, which are secured to the supplemental side pieces 11 and 12 and bent outwardly over the upper edges thereof, the flange 47 preventing dislodgment slidably of the cover in one direction when in one of its positionsthat is, when engaged with the main sides of the box. Displacementof the cover slidably in the opposite direction is prevented by a fourth flange 55, which is removably secured, so that it may be removed when the cover is to be removed from the box or when it is to be applied. To hold the flange 55 in place, it has the duplicate hook-plates 56 and 57 secured to its inner face, adjacent to the ends thereof, and which are adapted for slidable engagement with the duplicate plates 58 and 59, which are secured to the inner faces of the flanges 46 and 48 and bent outwardly across the free ends thereof. An additional hook-plate 60 is attached to the inner face of flange 55 at the upper edge or adjacent to the upper edge and is adapted to engage the up turned edge of plate 61, which lies in a recess in the end of the top of the box-cover, said plate 61 being attached to the under side of the top of the cover. This flange 55 is placed and removed by a movement in a plane at right angles to the plane of the top of the cover, and when it is in place and the coveris on the box it lies with its inner face against the outer face of the side 31.

When the cover is applied with the box in its folded condition, the cover is prevented from slidable displacement by plates 62 and 63, which are secured against the outer faces of the flanges 47 and 55 and depend therefrom to lie against the supplemental side pieces 13 and 14. Thus in either of its positions the cover can only be removed by first sliding the flange 55 from its place, and to prevent accidental displacement of this flange a latch is provided. This latch consists of a springwire 65, which is attached midway of its ends to the outer face of flange 55 and has its end portions bent at right angles and engaged through perforations 66 in the flange and adapted to lockingly engage with perforations or recesses 67, formed in the end of the top of the cover.

With this construction it will be seen that there is provided a construction wherein the parts may be readily adjusted. to their folded or their unfolded positions and that when so adjusted and having the cover in place they are held securely against displacement, and it will be understood that by applying a simple form of locking device to the removable flange 55 the box may be securely locked in eitherposition.

In practice various modifications of the specific construction shown may be made, and any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention.
